摘要： Disclosed herein is a method which enables permanent current junction of a tape-type oxide superconducting wire and suppresses reduction of its critical current. An end portion of a tape-type wire (10) to be joined is removed to expose oxide superconductor filaments. Another tape-type wire (10') to be joined with the wire (10) is processed in a similar manner. The tape-type wires (10, 10') are so superposed that the surfaces exposing the filaments face with each other, and the superposed portions are pressed in a direction perpendicular to principal surfaces of the tapes and heat treated at a temperature of 800.degree. to 900.degree. C., to be completely joined with each other.

摘要： Powder of not more than 1 &mgr;m in mean particle diameter is prepared to contain a mixture of superconducting phases mainly composed of 2212 phases of Bi—Sr—Ca—Cu or (Bi, Pb)—Sr—Ca—Cu and non-superconducting phases which is obtained by calcining and pulverizing raw material powder at least once, this powder is heat treated at a high temperature and thereafter coated with a metal to prepare a round wire by deformation processing, thereafter a tape type or flat type wire is prepared by deformation processing, then the wire is heat treated under conditions for allowing phase transformation of the 2212 phases of main superconducting phases to 2223 phases with facilitation of grain growth, thereafter the as-formed 2223 phases are highly densified by deformation processing or pressurization, and the wire is again heat treated so that the 2223 phases are strongly bonded with each other and the non-superconducting phases are finely dispersed. Thus, a bismuth oxide superconducting wire having a high critical current density is obtained.

摘要： According to an aspect, a tape-type high temperature superconducting wire is provided by applying compression work to a wire manufactured by drawing so that an oxide high temperature superconductor is divided into a plurality of superconductors by a stabilizing material of substantially equal thickness. According to another aspect, a high temperature superconducting wire is provided by packing a material which becomes a superconductor portion into a metal sheath which becomes the stabilizing material and applying drawing work thereto, followed by bundling an assembly of these wire in a metal sheath and applying drawing work thereto. The thickness of the superconductor portion is approximately 10% or less than the thickness of the wire. The critical current density is hardly decreased in the high temperature superconducting wire even if subjected to bending work.
